to improve devices of this character renthem comparatively simple and in-' c ipcnsive to manufacture, reliable and ellithis invention resides in the novel features of construction, combinations, formations and errungen'ients of parts to be hereinafter more particularly described, claimed and illustrated in the accompanying drawings, in which,

Figure 1 is an elevation of my invention looking at one side thereof. Fig. 2 is a similar view looking from the opposite side. Fig. 3 is a top plan view thereof. Fig. 4; N is an end view looking from one LliIBCtIOII: 5 is a similar view looking from anopposite direction. Fig. his a longitudinal sectional view taken on the line (3-(i of Fig. 3. Fig. 7 is a transverse sectional view taken on the line 7-7 of Fig, 1. Fig. 8 is a. horizontal sectional view taken on the line 88 of Fig. 1, and Fig. 9 is a similar view taken on the line 9-9 of Fig. 1.

Referring to the accompanying drawings by similar characters throughout the several 30 views. the numeral 10 designates generally my improved apparatus which consists of a frame 11 comprising opposite corner posts 12 and 13 of difierent types which posts are connected by intermediate cross beams 14 which extend longitudinally of the frame end transversely extending beams or bars 15 which connect the lower ends of the upright and provide a means for supporting the some." The upper ends of the uprights 12 mid T3 are connected by inclined cross bins 16 while to the inner sides of the said uprights and longitudinally extending bars are secured side plates 17 between which ate mounted the various clcmcnts for cleaning the grain. The upper ends of the plates 1 are extended above the inclined burs lfi und support thereon the side rails 18 of a. sooner ll 1 his hopper 19 consists of she 0d end plates 20 connected at their opposite edges 'oy downwardly converging aido rilutcs ill.

' i'lt is journaled in suitablebeersecured to the upper edges of the bars to adjacent the extensions of plates 17 and has keyed thereto a 24 which produce a blow 26 surrounds the fan 25 ill; s. ucln d the side fen casing while the Opposite ends to direct the grain in its passage their e1 and is secured at its opposite ends to the ends of the said extensions of the side plates 1?.

- The rear ends of the hopper 19 has formed thereon and extending rearwardly therefronna pair of apertured ears 2'? in which is journaled a shaft This shat't pivotally supports upon the hopper a plurality of closing plates 29 the terminals of which are arranged to close the slot 30 formed between the downwardly converging plates 21 are curved out wardly from the hopper for engagement with a plurality of pins 31 extending in staggered relation from a shaft 32 ournalcd in the side plates 17. This shaft 32 has keyed thereon upon the outside of the plates 17 a pulley 33 by means of which the said shaft is rotated. A'baille plate 33 1 s 1 fl ranged below the said hopper 19 and s I'Ulll upon the upper of a pair of riddles 35 a (l 36 supported by afrazne 37. This frame i)? consists of a pair of opposite side plates 38 connected at their lower edges by a hasc plate 39 which terminates in spaced relation from the rear ends thereof and at their rear .to the frame 37 and riddles am extremities by a connecting bar 40 and mu necting rod 41 one end of the riddle 37 rests upon the rod 41 while the opposite end is provided with a pair of trunnions engaged Within grooves 43 formed in the upper edges of the side plates 38. The frame 37 is connected to the side plates 17 by a pair of arms 4 pivoted to the side plates 17 and plates 38 respectively, while in order to transmit an oscillatory nun'erneut- 6 rc spectively, the said frame has pivoted to the opposite sides thereof a pair of pitmens 45 which engage at their outer ends eccentrics 46 kc ed to the before described fan shaft 22. plate 47 is secured to the lower side of the riddle 35 and serves to direct the opposite inclined sides projecting beyond grain upon the upper or rear ends of the riddle 36. A pair of chutes 50 and 51 are arranged below the riddle 36 and have their the terminals thereof as clearly illustrated in the longitudinalsectional view designated by Fig. 6 of the drawings. The chute 50 adapted to receive suehgrain as will pass through the openings in the upper portion of the screen 52 of the riddle 36, while a plate 53 is secured to the underside of the lower half of such riddle and is adapted to direct into the chute 51 such grain will pass through the openings in the lower por 4 tion of the screen of the riddle 36. it should be noted that only the heavy material will, fall through the openings while all foreign ,-'siibstances of a lighter nature together with a quantity of the smaller grain will pass over the end of'the riddle 36 and fall parallel to st-vertical plate 54 secured to the inner faces of the opposite side plates 17 by suitable spring cli 55.

The upper of the rails ha: located thereon bearing" f: in which is journalcd a shaft 57 arranged in spaced parallel relation from the lower end of the plate 54-. This shalt I)? has secured thereto a plurality of hubs 58 from which extend radial arn'is 59 the opposite terminals of which are apert-ured as at (50 to pro/i1 e a means of attaching thereto a sleeve 31. This slcove H1 is provided at its ppositc ends with circiunscribing flanges 62 ietiveen which are located a plurality of ooscly mounted rings (33 the peripheries of i 'h are serrated as at l'rl to produce a pluity of teeth which coact with toe plate a l and serve to engage the onions mixed will flraiu and remove the same therefrom. A shaft 3.3 is journaled in spaced parallel relation to the shaft 57 in suitable l ;earings lit; and has keyed thereon a brush HS the bristles 61 of which engage the serraiious l land rumor-c the onions therefrom causing them to fall upon a forwardly inclined plate from whence they will be directed to the exterior of the machine and into a suitable receptacle not shown in drawings. l

wall oi the chute 51 which/is rlesigua u; the numeral '71 terminates a distance brl )u' thc upper edge of the. opposite wall 72 the upper terminal oil the wall 2 1 has hinged thereto an extension 73 which may he turned either to en age the plate G l or thc u o1? the plate thereby directing the n cithcr into the said chute 51. or into a chute N form {d by a pair of downu'ardly converging pla s 75 and 76 the l on nzcr of which is secur i to the upper edge ot' the plaic 70 while t ic latter secured to the plate 71 adjacent its pivotal connection with the plate 7 the lrr-wier edges 01 the plates and 76 are spaced apart to produce a slot 7 thwue'h which the contents of the ehutc Tl are directed between a pair of rollers I23 and 79 l-:e ,'ed to shafts 8b and 81 journaled at their opposite ends in suitable brace bars ll located above the transrcise oars 15.

A double hiuvper is located below the rollers 78 and 75) and comprises a plurality oi downwardly converging plates 84 and 85. The upper ends of the outer of the plates 8i and are secured one beneath theshaft which sluiports the roller 78 and the opposite to a point in advance of brush 86 lie ed upon a shaft 87 journaled in suitable l'iearings 88 scoured to the upper edges of the bars 1 adjacent the uprights 12. Fhe upper ends of the plates 8s: and located at. the inner sides of the said double hopper tcrn'iinate below the shaft which supports the roller 79 at which point they are secured together producing two inclined surlleariugs 81-5 scoured to the upper edges otfaces which direct the contents thereof through the discharge openings formed in their bottoms.

The rollers 78 and 79 are pro ided with flexible coverings 8S and 59 which serve to prevent any injury to the grain while pass lug therethrough while the last mentioned covering is of such nature that the cocltel contained within the grain will adhere thereto and upon the rotation of the said roller will be scraped therefrom by the pre viously mentioned brush S6. A balile i0 is hinged at the meeting ends oi the inner plates 84 and S5 and may he moved to pro ject into either of the ciunpartnirnts i l and. 5 located between the said inner and outer plates Sland 5. ii. stub shait 93 is journaled in a suitablebearing 9? attached to one of the uprights 1 5 and has keyed to its outer extremity a pullev 97 A cable i l; passes over this pulley and over a similar pulley 9T oi less diameicr keyed to the terminal of the shaft 22 whereby power is transmitted to the fan. The before men tioned pulley 233 lrictionally engages the belt J6 and imparts a rotary movemei'i t to the shai t 3'. thereby providing a means for operatinp the plates il The shaft 80 which supporls the roller in has keyed thereon a pulley 98 which is connected to the shaft through the medium of a belt U9 and pul lc lol kc ved to the said last mentioned shalt. The shaft which supports the roller T has further keyed thereon a gear wheel 101 which meshes with a similar gear wheel h 3 keyed to the shaft h'll which supports the roller T9. The opposite end of this last nuuiionril shaft has keyed to its opposite end a pulley h 3 over which pas a cable 10%. This cable All also pass-vs over pulleys 105. 106 and 10? kcvcd lo the adjacent ends-of the shafts .35. I13 and 8? re- SPkCtlYil) which serve to impart the proper rotary movement to the said shafts and the.

operating means connected thereto.

Fron thc foregoing disclosures taken in ronnenion with the accompanying drawings it will he manifest that a grain cleaninc apparatus of the nature described is produced which will l'uliil all al the necessary requirements ol' such '1 device.

Having thus fully described this inven tion what 1 claim is new and desire to protect by Letters Patent is:

iv in an apparatus of the class described, the combination with means for separating relatively large particles of foreign matter from the grain, and means located below the first mentioned means for separating the relatively smaller particles from the grain, of a hopper and a chute located between the two separating means and divergin relatively to each other, the hopper con noting the grain and smaller particles of foreign matter and the chute conducting the separatiil particles of larger foreign matter away from the first separating means.

2. in an apparatus of the class described, the combination with two distinct separating means spaced apart and located one above the other, of a hopper and a chute located between the two separating means, the upper end of the chute meeting the upper end of the hopper, said chute and hopper diverging relatively to each other.

3. .in a grain separator, the combination with a frame. of a vertically disposed plate .nninntccl within the frame, a. roller mounted :nljaccnt said plate and provided with a pluralit; ol' peripherally arranged toothed rings adapted to cooperate with the plate in the revolution of the roller to remove foreign substances from the grain passing said plate. 11 depending hopper located be low the plate and roller, and adapted to have the grain pass therethrough, a chute located below the roller with its upper end meet ng ti 2 upper end of the hopper, said chute ;tending in an opposite direction from the. hopper and designed to convey Foreign substanccs from the roller, and a. pair ot rollers mounted below the hopper, one of said rollers having it covering de signed to remove any foreign substance which may remain in the grain passing through the hopper.

in testimony whereof, I afiix my signnture. in presence of two witnesses.
